Conteúdo: | Single cross seedlings of the male progenitor of the double cross hybrid, BR 201, were grown for seven days in a complete nutrient solution prior in evaluating the kinetics of nitrate uptake under varying periods of phosphorus deficiency. Nitrate uptake decreased 60% after a short period of phosphorus starvation (2 days) and ceased when phosphorus was withheld longer than six days. Nitrate uptake resumed after phosphorus (P) was re-supplied, but the time required and extent of recovery depended on the length of phosphorus starvation.
